well a few things:
crystal, the character you see, is a favorite victim of ALICE’s. She doesnt always get tormented by ALICE, sometimes its just trolling, scaring, or somewhat more harmless mannerisms. This is to make the suspense of IF ALICE will torment her more unexpected and thus more terrifying.
Crystal also is an a relationship with Seraphina, a character i may draw again pretty soon (her hair, btw, is based on Super Sonic’s quills, and she happens to be a perfect foil for Crystal: a rebel, reckless, and slightly vulgar, but also energetic, charasmatic and very sweet to the core)
Crystal’s personality, as far as i can describe, is a blend of Peppino (Pizza Tower) and Abbie’s (FPE) personalities. She also happens to have a deep bond woth the Sonic franchise.
